Question 19

Zinc powder reacts with excess silver nitrate solution according to the equation:

Zn(s)+2AgNO3(aq)→Zn(NO3)2(aq)+2Ag(s) \mathrm{Zn(s) + 2AgNO_3(aq) \rightarrow Zn(NO_3)_2(aq) + 2Ag(s)} Zn(s)+2AgNO3​(aq)→Zn(NO3​)2​(aq)+2Ag(s)

A 9.75 g sample of zinc reacts completely.

Relative atomic masses: Zn=65\mathrm{Zn} = 65Zn=65, Ag=108\mathrm{Ag} = 108Ag=108

Calculate the maximum mass of silver that could be obtained.
